Not that separate amps aren't superior, they generally are, but why do it if there is an alternative? I started doing this just after I got into home theater, about 12 years ago. But I got away from it because I couldn't stand the thought of my receiver amps sitting idle. It seemed like a waste of property and power. Also, why have a unit that cross-contaminates itself by having power amps and signal sections in the same box, if you have the power amp/preamp alternative? So I decided to go with amps and preamp processors. But I'm wondering why anyone would spend $3000 on a top line receiver now only to buy separate amps for it? Why not just buy a preamp and use it with separate amps? Is it most of the time a case of someone buying a receiver, finding out it's amps aren't that good, and then adding the separate power amps?
